Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce damages of an obstacle and a self vehicle by absorbing the shock energy. SOLUTION: Racks 13 are arranged on both sides of a hollow aluminum alloy member 11 and a slider 12. A cylindrical body 40 with a pin 15 and a coil spring 16 being inserted therein is arranged inside the slider 12. Two or more grooves 14 are formed in the rack 13. When an air cylinder 17 is contracted, the slider 12 is moved forwardly. As the slider 12 is moved, the hollow aluminum alloy member 11, the pin 15 and the coil spring 16 are moved forwardly. The pin 15 is urged to the rack 13 side by the coil spring 16 while being moved forwardly, and engaged with a first groove 14. Disengagement from the first groove and engagement to a second groove 14 adjacent on the front side are repeated. COPYRIGHT: (C)2011,JPO&INPIT
